Abraham's sacred fishes

Abram couldn't accept the pagan gods
of the Assyrian king Nimrod. So the
king threw him into the fire. But
Abram's god made the fire into water,
the burning coal into carps.
Consequently the fishes are sacred, and
if you eat of them, you'll become blind
(if you're not a cat). But you can feed
them. But not with bread, as it swells
inside the stomach. Sacred or not, fishes
are stupid and they eat and eat even
when full. People throw bread and
simits (salty crisps) at them to see
them fight, watching them push the
simits around like circus fishes.
